Woodpeckers may seek out homes with aluminum siding or tin roofs because these surfaces echo their drumming. Homes with wood siding are more frequently targeted as roosting areas or for food sources. If you have insects living in the exposed wood in your home, the birds are likely looking for a snack, in which case your best option is to hire an exterminator.

Keeping your pool cover clean is a good way to keep smaller animals from running across it or using it as shelter. Small animals may use leaf debris on top of the cover to hide. Cleaning also removes nuts that may fall from a nearby tree that could otherwise be a tempting snack for some animals, like squirrels. 

When woodpeckers start banging on your walls or roof, they are probably looking for insects to eat, storing nuts for winter, drilling a hole to make a nest, or communicating with other birds to establish territory or find a mate.

The size of the hole can help determine the reason for the pecking. Small irregular holes are a result of insect hunts. Acorn holes are more consistently sized and often fitted with a nut in the middle. Nest holes are large and have rounded edges. If the bird is pecking to mark its territory or attract a mate, it may leave dents rather than holes, and the noise will stop when the mating season starts in spring.

Bird and bat pest control involves assessing the site, installing deterrents, sealing entry points, and, in some cases, safely removing infestations following regulatory guidelines.
